Hi everyone.
What I talk below is in VMM level.
I got a pseudo address of guest OS, how can I get the machion address? 
I mean I want to get the content in that address of memory.
There maybe some functions to do this work, does anyone knows?
Thanks.

In a PV domain you can use the p2m table to look up the mapping. I don't
think the mapping is exposed to HVM domains at all.
